Abstract (en)
[origin: US2008101298A1] We describe an example system including a wireless cellular channel to transmit voice data associated with a call between a server and a wireless device. A wireless signaling channel, distinct from the wireless cellular channel, transmits supplementary signaling packets between the server and the wireless device.
